Opel corsa E 2017 1.3 TCM problem

[Panathaole]

Hi

I have an opel corsa E 2017 1.3lt with marelli tcm auto gearbox, in box there is engage gearspeed but in dush I hame N and car starts....(after few secs turn off because off the gear in gearbox)

No dtcs in engine and in tcm ecus....

Do you know anything about that?

Hi. See the gear position in the parameters. Sometimes the dash shows N and there is one gear left in the gearbox parameters. And it doesn't show an error. Also check physically if you have N if the car is going to push forward or backward. If so, you can try a short starter or car start.

In live data, I see no gear engage in gearbox, the ecu doesn't see any gear engage, is there any sensor that shows which gear is in the box?

Can you make gearbox addaptation with any tool? Does it have any clutch disk changed recently? Or gearbox transmission oil leak? Can be some wearing on clutch disk and it needs to readdapt the gearbox, in order to change gears ok. Yes, the gb has a sensor to detect gear shifter and show in dash the actual gear.

I use gds and launch(dz) have the same adaption option....

Nothing change..... I make depression, new disk installation and calibration still the same.....
I see in live data oil pressure 49 psi? Is that normal?

I try with launch to make gear engage - change, I can hear the motor moving, but can't get any gear.... ecu still see N....

I don't know the normal fluid pressure. Did you do addaptation, put in P and take off the battery? And after repowering it, to see if dash can show P? Check the GB ecu plugs, clean and reconnect them and see what happends...
If you have access, take off the gb ecu and take a look inside

It can't put any gear......

Is in N position, when I press selector, it try to put a gear but it can't...

Maybe hydraulic valve problem???

In diagnosis I see tcm T57..... Owner looking for other one.....
Is this ecu closable? Io terminal can read it?

That is why i've told you to open the tcm ecu
